Abstract (en)

[origin: DE102006003283A1] The method involves forming a layer (58), which inhibits diffusion of a dopant. The dopant is penetrated into the layer on a portion of the surface of a semiconductor component material (50). A diffusion-inhibiting layer in a highly doped region (62) is partially removed. The dopant source (66) is formed on the diffusion-inhibiting layer in the highly doped region and the dopant is diffused from the dopant source into the semiconductor component material. The dopant is made up of phosphorus or boron.
